Question

If one DNA strand is 5'-GGCATTACACTAGGCCT-3', what is the complementary srand?
​

Answer 1

3' - CCGTAATGTGATCCGGA - 5'

Step-by-step explanation:

In DNA, the leading strand builds from a 5' to 3' direction and the lagging strand (complementary strand) must build from a 3' to 5' direction.

The base-pairing rules for DNA are:

- adenine always pairs to thymine (A to T) (T to A)

- guanine always pairs to cytosine (G to C) (C to G)
